摘要 |
The invention is relative to an electrolysis cell for the anodic dissolution of metals, in particular of metals characterised by a relatively high oxidation potential, such as copper, or metals with high hydrogen overpotential, having the purpose of restoring the concentration of metal ions in galvanic baths employed in electroplating processes with insoluble anode. The cell of the invention comprises an anodic compartment, wherein the metal to be dissolved acts as a consumable anode, and a cathodic compartment, containing a cathode for hydrogen evolution, separated by an anion-exchange membrane. The coupling of the cell of the invention with an electroplating cell allows a strong simplification of the overall process and a sensible reduction in the relative costs. |
